<u>the correct question is</u>
The denarius was a unit of currency in ancient rome. Suppose it costs the roman government 10 denarii per day to support 4 legionaries and 4 archers. It only costs 5 denarii per day to support 2 legionaries and 2 archers. Use a system of linear equations in two variables. Can we solve for a unique cost for each soldier?
Let
x-------> the cost to support a legionary per day
y-------> the cost to support an archer per day
we know that
4x+4y=10 ---------> equation 1
2x+2y=5 ---------> equation 2
If you multiply equation 1 by 2
2*(2x+2y)=2*5-----------> 4x+4y=10
so
equation 1 and equation 2 are the same
The system has infinite solutions-------> Is a consistent dependent system
therefore
<u>the answer is</u>
We cannot solve for a unique cost for each soldier, because there are infinite solutions.
Answer:
23: 21
25: 1
Step-by-step explanation:
<u>Question 23</u>:
1) add the whole numbers together: 15+5=20
2)To add fractions, both need to have the same denominator. Find a number that is a multiple of both denominators (in this case 55)
→ 
(multiply the numerator and denominator by 5)
→ 
(multiply the numerator and denominator by 11)
3) add the fractions together
+ = 
(add the numerators)
4) Turn the improper fraction into a mixed number
Divide 78 by 55. You'll get a whole number and a remainder. The remainder is the new numerator: In this case 55 enters 78 once with a remainder of 23. Therefore:
1
5) Add the whole numbers together to get the final answer:
20+1= 21
Answer: 21
<u>Question 25</u>:
Follow the above steps but subtract instead of adding
